Thanks Audog, I guess when in doubt read the owners manual and go the the child restraint section in my book on 3-41 (I did that after posting for help). On the 2012 there are 2 buttons to push at the same time. Since I had never had to push 2 before and the second one is slightly hidden if you are not looking for it.........I didn't know.If it's like the 11, press the little button and keep it pressed while removing the headrest. I have to lean the seat forward to completely remove the rear headrest.
Thanks for responding LadyInBlue! On the 2012 there are 2 buttons and I missed seeing the second one.I removed mine to install the rear seatcovers and I tilted the seat forward so there is plenty if room and after you get them past the detent, just keep pulling. They will pull all the way out.
